In olden times, spices were often given as good luck charms to bridal couples. Three specifically are Whole Nutmeg, Rosemary Leaves, and Star Anise:

Whole Nutmeg: An old European belief is that as long as there is a whole, sound nutmeg in the kitchen, the marriage will also be sound. Many whole nutmegs will be grated and used throughout the marriage, but one should always be left in the kitchen whole.

Rosemary Loaves: Rosemary was believed to improve the memory in the ancient Greek studies of mnemonics. Around the Middle Ages, certainly by the time of Shakespeare, rosemary became the herb of lovers. It embodies the remembrance of all that is good about love through the many years of marriage.

Star Anise: Star anise has a wonderful sweet, licorice flavor. The whole stars are very beautiful, but also very rare. Most stars are broken during processing. A beautiful, many-pointed whole anise star has long been given as a keepsake to the bridal couple in the parts of China where the anise trees grow, It signifies both the spiritual unity of the many points of the couple coming together as one, and the tenaciousness of the rare and beautiful Star that stays whole and perfect.
